I thought the ending of my book happened really fast. There was a really big climax with a lot of anticipation, then it ended and resolved the solution within one chapter. I enjoyed how it ended, but it was just to soon and left to many questions unanswered. I also thought the killer was completely random and would've made more sense if Stone would have been the killer. I understand why the author chose the girl to be the school shooter, but it just left to many questions unanswered for me.
